摘要

By carrying out a metathetic reaction between sodium succinate and CdCl_2 or CdBr_2 in an n-butanol-water mixture, two novel open-framework cadmium succinates, [NA_3Cd_5(C_4H_4O_4)_6Cl], I, and [Na_3Cd_5(C_4H_4O_4)_6Br], II, have been isolated. Both of these compounds possess interpenetrating three-dimensional open-framework structures wherein tetrahedral Cl(Br)Cd_4O_(24) clusters are connected by succinate linkages. The tetrahedral cluster itself is formed of four CdO_6 octahedra surrounding a halogen atom. The three-dimensional cadmium succinate framework incorporates sodium ions. Four sodiums surround the second nearest neighbor halogen atom, forming a Na_4Cl(Br) tetrahedron.
